Abstract Geminal ( gem −) disubstitution in heterocyclic monomers is an effective strategy to enhance polymer chemical recyclability by lowering their ceiling temperatures. However, the effects of specific substitution patterns on monomer's reactivity and resulting polymer's properties are largely unexplored. Here we show that, systematically installing ‐dimethyl groups onto ϵ‐caprolactam (monomer nylon 6) from α ϵ positions, both redesigned lactam ‐nylon 6’s highly sensitive position, with...
Background and Objective S100A8 S100A9, two members of the S100 protein family, have been reported in association with tumor cell differentiation progression. Previous study has showed that their expression stromal cells colorectal carcinoma (CRC) is associated size. Here, we investigated clinical significances S100A9 CRC underlying molecular mechanisms. Methods Expression matching distal normal tissues were measured by reverse transcriptase polymerase chain reaction (RT-PCR),...
The polymer binders used in most lithium-ion batteries (LIBs) serve only a structural role, but there are exciting opportunities to increase performance by using polymers with combined electronic and ionic conductivity. To this end, here we examine dihexyl-substituted poly(3,4-propylenedioxythiophene) (PProDOT-Hx2) as an electrochemically stable π-conjugated that becomes electrically conductive (up 0.1 S cm–1) upon electrochemical doping the potential range of 3.2 4.5 V (vs Li/Li+). Because...
Abstract In the past decade, direct arylation polymerization (DArP) has rapidly developed as a sustainable synthetic protocol for cost‐effective, atom‐economical preparation of conjugated polymers. By circumventing monomer functionalization with toxic transmetallating reagents such organostannane and organoboron required Stille‐Migita Suzuki‐Miyaura methods, DArP proceeds through metal‐catalyzed CH activation pathway high‐performance polymer materials. This review evaluates development...
The S100A9 protein, a member of the S100 protein family, is often upregulated in various types cancer, including hepatocellular carcinoma (HCC). acts as danger signal when secreted to extracellular space and thought play an important role during tumorigenesis. Despite this fact, little known about effects tumor microenvironment on HCC. Therefore, study, we investigated exogenous proliferation invasion HepG2 HCC cells, well molecular mechanisms underlying these effects. Our results...
The S100A6 protein, a member of the S100 protein family, is overexpressed in many tumors including colorectal carcinoma (CRC). Although recent studies showed that elevated expression was associated with stage and lymphatic permeation CRC, little known about whether how contributes to CRC development. Here we investigated tissues cell lines, explored molecular mechanisms underlying role development by examining proliferation migration vitro, tumorigenicity nude mice. results show markedly...
Green solvents, notably cyclopentyl methylether (CPME), are found to be highly effective in Direct Arylation Polymerization (DArP).
We report the application of green solvents in DArP and structure-dependent β-defect formation due to an ester directing group.
Organic electroactive materials that can be processed using simple alcohols, such as ethanol and 1-butanol, are highly desired, since these solvents sourced from biomass present lower hazards for human environmental health. Herein, we report the first class of poly(3-alkylamidethiophenes) (P3AAT) synthesized via sustainable method direct arylation polymerization (DArP) green, solvents. The unprecedented synthesis P3AAT reveals superiority DArP, readily prepared in only three steps with an Mn...
Direct arylation polymerization (DArP) has allowed for the facile preparation of a variety conjugated polymer architectures. Because DArP proceeds through C–H activation pathway, selectivity only desired bond certain monomers remained challenge. Low can lead to introduction various structural defects. The development conditions use additives, screening and design phosphine ligands, precatalysts provided condition sets that work some afford polymers with minimization In addition modifying...
For over a decade, Direct Arylation Polymerization (DArP) has been demonstrated to be an eco-friendly, facile, and low-cost alternative conventional methodologies such as Stille polymerization for conjugated polymer synthesis. By accessing through C–H activation pathway, DArP offers reduction of synthetic steps while eliminating the generation stoichiometric, highly toxic organotin byproducts. However, major component in these reactions, solvents most prevalently employed are hazardous...
As an effort to replace palladium catalysts, we report the first example of a Copper-catalyzed Direct Arylation Polymerization (DArP).
Bone morphogenetic proteins (BMPs) are members of the TGF-β superfamily signaling factors. Expression several BMPs (BMP2, BMP4, and BMP7) is correlated to poor prognosis in gastric cancer patients. The function BMP9, latest discovered most powerful osteogenetic factor, relatively unclear. In this report, we investigated expression, underlying molecular mechanisms BMP9 cancer. results show that expression was markedly decreased tissues cell lines. Enforced lines SGC-7901 MNK-45 increased...
Over the past decade, direct arylation polymerization (DArP) has emerged as a facile and sustainable methodology for synthesis of conjugated polymers. Recently, we developed Cu-catalyzed DArP (Cu-DArP) low-cost, Pd-free synthetic pathway, which enables polymers to be synthesized with high molecular weights minimization defects. However, lack study on use Cu-precatalysts in small-molecule poses significant limitations Cu-DArP potentially overtake conventional Pd-catalyzed methodology, such...
Direct arylation polymerization (DArP) has enabled the more sustainable synthesis of conjugated polymers through reduction waste, elimination toxic and hazardous byproducts, overall synthetic steps. However, DArP methodologies have almost exclusively relied on use noble metal catalysts, such as those with Pd, counter to efforts toward sustainability. Herein, we report optimized a flourinated arylene copolymer via using low-cost, copper catalyst. Through optimization conditions, are able...
The first report on direct arylation polymerization with copper catalysts and aryl-bromide monomers expands the sustainability practicality of DArP.
Despite the inherent sustainability direct arylation polymerization (DArP) offers through a C–H activation pathway, use of expensive homogeneous Pd catalysts remains problematic for large-scale conjugated polymer (CP) synthesis. Herein, first report on recycling heterogeneous CP synthesis using DArP is presented. We found SiliaCat Pd-DPP to be highly efficient and recyclable catalyst multi-batch providing CPs with molecular weights (Mn) up 82 kg/mol even after being recycled three times....
Aeromagnetic surveys are widely used in geological exploration, mineral resource assessment, environmental monitoring, military reconnaissance, and other areas. It is necessary to perform magnetic compensation for interference these fields. In recent years, large unmanned aerial vehicles (UAVs) have been more suitable detection missions because of the greater loads they can carry. This article proposes some methods multiload UAVs. Because platform instrument noise, standard deviations (stds)...
